Get Files Inside a folder in Document directory in iPhone

Question

I am new to iPhone,

I made an app in which, i am downloading a book and storing it in a folder called book1Folder which is inside Document directory.

now i wants name of all books in my array, there are 2 books inside a book1Folder but when i write this code it shows me array count is 3.

Here is my code snippet,

-(void)viewWillAppear:(BOOL)animated{
    NSString *files;
    NSString *Dir=[self applicationDocumentsDirectory];
    Dir=[Dir stringByAppendingPathComponent:@"book1Folder"];

    NSDirectoryEnumerator *direnum = [[NSFileManager defaultManager] enumeratorAtPath:Dir];

    Downloadedepubs = [[NSMutableArray alloc]init];
    while(files = [direnum nextObject])
    {
        if([[files pathExtension] isEqualToString:@"epub"])
            NSLog(@"files=%@",files);
            [Downloadedepubs addObject:files];
    }
}

My log shows only name of 2 book, but when i loop through array it contains 3 objects.

[Downloadedepubs ObjectAtIndex:0]=.DS_Store;
[Downloadedepubs ObjectAtIndex:1]=abcd;
[Downloadedepubs ObjectAtIndex:2]=pqrs;

What is that .DS_Store why it is coming ?

Any help will be appreciated.

Answer 1

Get your if block in curly brackets. It affects only first line after if.

Like below;

if([[files pathExtension] isEqualToString:@"epub"]) {
            NSLog(@"files=%@",files);
            [Downloadedepubs addObject:files];
}
